Answer:
There appears to be a difference between the pulse rates from samples of adult males and females. The average pulse rate of males is 63.75 while that of females is 75.875.
Coefficient of Variation (male) = 33.44%
Coefficient of variation (female) = 28.35%
Step-by-step explanation:
Mean (male) = 
Mean (female) = 
Standard Deviation (male) = 
Standard Deviation (female) = 
Coefficient of Variation = 
For male, CV = 
%
For female, CV = 
%
Comparison : Pulse rates of males has more variability than that of females since it has a greater coefficient of variation.
Answer:
No.
Step-by-step explanation:
It does not pass the vertical line test, so the relation is not a function. This is because there are x-values that have several y-values. To be a function, a relation must have x-values that only have one y-value each.
Hope this helps!
Two angles are said to be linear if they are adjacent angles formed by two intersecting lines. The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.
Sum of linear pair of angles = 180°
so
<EFG + <GFH = 180°
2n + 21 + 4n + 15 = 180°
6n + 36 = 180°
6n = 144
n = 24
<EFG = 2(24) + 21 = 69°
<GFH = 4n + 15 = 4(24) + 15 = 111°
We'll have to assume that interest is charged annually.
interest = i = p*r*t, where p is the initial amount ($25000), r is the annual interest rate as a decimal fraction, and t is the length of time, in years.
Then $2625 = $25000*0.035*t. Solve for t:
$2625
------------ = 0.035t = 0.105. Dividing both sides by 0.035, we get
$25000
t = 3 years (answer)
